Where to begin
These guides build on each other. The first explains what it means to compare two player prop markets honestly. The second applies that workflow to pick'em line shopping. The last two cover the odds math underneath: converting published prices into probabilities, removing sportsbook margin, and the narrow conditions under which a percentage edge is defensible.
An edge only exists when the player, statistic, side, event, and strike match exactly. A different strike is a different outcome, and no amount of price math turns it back into the same one.
How to compare DFS player props
The core workflow: match the identity of the market, compare the strike, translate the published price into a break-even probability, weigh the quality of your reference, and recheck before you submit. Also covers the difference between a line advantage and a price advantage, the distinction that prevents most false precision.
PrizePicks line shopping
How to check a PrizePicks strike against Underdog, Betr, DraftKings Pick6, and two-sided reference markets without accidentally comparing markets that settle differently.
No-vig probability explained
American odds to implied probability, why two sides sum to more than 100%, and how removing that margin produces the cleaner reference number used in every exact-strike comparison.
Exact-strike edge methodology
The full calculation PROPD publishes: reference no-vig probability minus target break-even probability. Also covers how evidence tiers work and what the board deliberately refuses to compute.
